What evidence made you delete a feature you had already built?

Shipping a feature creates a weird emotional tax. The code exists, the screenshots look good, and suddenly sunk cost starts impersonating customer value.

The strongest deletion evidence I have seen is not a low click count by itself. It is watching the feature add decisions, setup, or confusion without improving the user’s actual outcome. Sometimes the cleanest roadmap move is subtraction.

What convinced you to remove something you had already invested in?
